How to Attach a Coulter Wheel to a Drawbar

When operating with a plow, coulter wheels slice hardened soil.

A coulter wheel is a rolling blade that attaches to farm implements or construction equipment for the purpose of making deep vertical cuts into the earth or even concrete. From making the initial cut into hardened soil when plowing to creating an earthen crease into which fertilizer is disbursed, the coulter wheel enhances the performance of farm equipment. Furthermore, it is useful in both construction and demolitions for breaking up concrete and cement foundations. A secure attachment to a tractor drawbar is essential if the coulter wheel is to function properly.

Instructions

1. Measure the height of your drawbar and determine the center of gravity for your coulter wheel. The center of gravity must be lower than the drawbar. Adjust the height accordingly.

2. Drill two 1/8-inch in diameter holes in the drawbar if they are not presently there. Many coulter wheels require a bracket for mounting.

3. Attach the bracket to the drawbar using u-bolts and nuts suitable in size for your holes. Tighten the connectors with a torque wrench set to 150 foot-pounds. A foot-pound is a measure of the energy required to move one pound of weight over a distance of one foot.

4. Join the coulter wheel beam to the bracket, using hex nuts, hex bolts and flat washers. The beam and bracket should be coupled at two spots minimally. Tighten the assemblies to a torque value of 270 foot-pounds.

5. Lubricate the entire assembly with grease where the coulter wheel is attached. This will ensure smooth operation.

Tips & Warnings

• Check with the manufacturer regarding the coulter wheel function when attached directly to the drawbar.

• Consult the operator instructions of both the tractor and the coulter wheel before attaching to the drawbar. Each model is configured differently, and the particular constructions must be accounted for.

• Coulter wheels possess sharp and dangerous moving parts. Follow the manufacturer’s safety guidelines.
